Definitions

  • the present patent application relates to a hood for installation above cooktops, which is frontally provided with a virtual barrier capable of automatically switching on the lamps of the hood and/or activating the fan, whenever the virtual barrier is interrupted.
  • the hood according to the present invention has been designed as a specific solution to the excessive energy consumption typical of this type of devices.
  • the user normally puts a pan on the cooktop, switches on the lamps located in the lower part of the hood to provide light directly onto the cooktop and activates the fan at medium-high rotation speed.
  • the lamps and the fan remain switched on until cooking is completed, even if the user approaches the cooktop on occasional basis to check the food.
  • the hood according to the present invention has been devised, which is capable of automatically switching on the lamps and activating the fan at high rotation speed only when necessary.
  • the hood according to the present invention has been provided with an electronic device capable of activating a virtual barrier that extends downwards from the front edge of the hood, thus covering the entire space between the hood and the cooktop.
  • the barrier must be activated when cooking starts, by means of a suitable button located on the frame of the hood, next to the traditional controls used for the manual activation of the lamps and the fan.
  • the interference causes the interruption of the virtual barrier.
  • Such an interruption is translated as a signal of the user's presence next to the cooktop.
  • the hood immediately and automatically responds by activating the fan and switching on the lamps.
  • the hood is also provided with a timer that favours the automatic deactivation of the fan and the automatic switching off of the lamps when the set time has elapsed after the end of the interruption of the virtual barrier.
  • the elapsing of time is considered as a confirmation of the fact that the user has left and therefore it is no longer necessary to keep the lamps and the fan in operation.
  • the switching on/off can occur gradually in order to reduce the visual stress for the user's eyes.
  • the hood according to the present invention features several advantages when compared to the traditional technology.
  • the virtual barrier of the hood according to the present invention can also be programmed so as to provide the switching on of the lamps and the activation of the fan on a separate basis.
  • the hood according to the present invention can also feature the virtual barrier on the remaining sides of the hood (apart from the front edge).
  • the virtual barrier can be of different types, according to the technology used: optical barrier (by means of optoelectronic sensors, cameras, etc.) or, alternatively, a barrier obtained with infrared rays or ultrasounds.
  • the hood (1) is provided with a device (2) capable of activating a virtual barrier (B) under the front edge (1a) of the hood (1) towards the cooktop by means of the corresponding switch (2a).
  • the interruption of the virtual barrier (B) determines the immediate automatic switching on of the lamps (3) of the hood (1) and/or the activation of the fan (4).
  • the hood according to the present invention is provided with an electronic device actuated by the manual ON/OFF switch (2a), featuring a management and control microprocessor (not shown in the enclosed figures) which is interfaced with the activation controls of the lamps and the fan and with a timer by means of the activation means of the virtual barrier.
  • a management and control microprocessor not shown in the enclosed figures
  • the interruption of the barrier by the user sends the microprocessor a signal for the activation of the lamps and/or the fan, according to the selected operating mode.
  • the microprocessor automatically determines the deactivation of the lamps and the fan when the set time has elapsed after the last interruption of the virtual barrier.
